Button assembly with status indicator and programmable backlighting

Abstract

A configurable switch matrix assembly with button assembly is disclosed for keypads used in devices such as primary control points for automation systems in homes vehicles, or commercial environments. The configurable switch matrix assembly preferably includes a frame for supporting a plurality of positionable cross members and optionally a baffle. The cross members and frame each preferably include cantilevers which can be deflected by pressing the button assemblies to activate switches associated with the keypad. Dynamic status lights and back lights may provide illumination of varying colors and intensities. Button labels may be easily replaced in the button assemblies. Button assemblies of different sizes and shapes may be easily attached to the configurable switch matrix assembly in various configurations without the need for different attaching devices for each situation and / or environment.

Description

[0001] This application is a continuation-in-part of U.S. patent application Ser. No. 10 / 024,129, filed Dec. 17, 2001, entitled Switch Matrix.[0002] 1. The Field of the Invention[0003] The present invention relates generally to keypad devices, and more particularly, but not necessarily entirely, to a switch matrix which allows the use of variable key positions and key sizes on the keypad and to the use of such devices.[0004] 2. Background Art[0005] It is common practice to provide keypads consisting of one or more keys arranged for entry of data or performing functions such as activating switches. Keypads are used for various types of electronic devices such as user interfaces for home automation and security systems, calculators, telephones, etc. Keypads commonly include an assembly of various parts maintained in a housing.[0006] For example, FIG. 1 shows a keypad, generally indicated at 2, known in the art for use as a primary control point for automation systems used in areas suc...

AI Technical Summary

Benefits of technology

[0008] In view of the foregoing state of the art, it would be an advancement in the art to provide a switch matrix which is capable of being used with keys of different sizes and shapes. It would be a further advancement in the art to provide a switch matrix which allows the keys to be arranged in different configurations using differing numbers of keys. It would also be an advancement in the art to provide a switch matrix which allows the keys to be easily installed and replaced without damaging the matrix.

Problems solved by technology

Removal of the attaching plate 6 is a difficult task which may require the services of a professional or use of specialized equipment since the attaching plate 6 is fixed to the housing 4 and is not designed to be easily removed without damaging the attaching plate 6 or the housing 4.
